Grimm is an American police procedural fantasy drama for television. It debuted in the U.S. on NBC on October 28, 2011, and airs on CTV in Canada and in Europe, Asia and elsewhere in the Americas on such networks as Universal Channel and Watch. The show has been described as "a cop drama—with a twist... a dark and fantastical project about a world in which characters inspired by Grimms' Fairy Tales exist", although the stories and characters inspiring the show are also drawn from other sources.

Homicide Detective Nick Burkhardt of the Portland Police Bureau learns he is descended from a line of "guardians" known as "Grimms," charged with keeping balance between humanity and the mythological creatures (called "Wesen") of the world. Throughout the episodes, he must battle against an assortment of dangerous creatures, with help from his friend Monroe (who is a reformed creature), and his partner Detective Hank Griffin.
